2D slice selective T1ρ and T2ρ maps of the brain
acquired in a volunteer. Six preparation periods of 0, 16, 32, 48, 64 and 80 ms
consisting of 0, 4, 8, 12, 16 and 20 GOIA-W(16,4) pulses were acquired for 20
slices with 2D EPI-SE at 2×2×5 mm3 resolution in 1:17
min. T1ρ map shows good uniformity in all slices, while T2ρ map
shows signal loss in slices at the base of the skull in regions with large
susceptibility anisotropy. The coronal views on the right side indicate the
prescription of slices and show no magnetization history between neighboring
slices.
